Product Summary

The AD7870CQ is a fast, complete, 12-bit A/D converter. It consists of a track/hold amplifier, 8μs successive-approximation ADC, 3 V buried Zener reference and versatile interface logic. The AD7870CQ features a self-contained internalclock which is laser trimmed to guarantee accurate control of conversion time. No external clock timing components are required; the on-chip clock may he overridden by an externalclock if required.
